UNITED snares PATEN To cal! whom it may concemr Be it known that I, VVrLLiAM P. BEOH- DOL'l, a citizen ofthe United States, residing at Portland, in the county of Jay and State of Indiana, have invented certain new and useful Improvements in Heating'Stoves, of which the following is a specification.

This invention relates to heating stoves;

The primary object of the invention is to provide a stove of this character constructed so as to produce a maximum amount of heat with a minimum consumption of fuel.

Another object is to provide a stove with a system of air pipes so arranged in the stove as to conduct cold air from below the bottom of the stove up through the stove and expose it to the heat in the grate and the fire bowl, the pipes extending upwards to the upper end of the combustion chamber and discharging through the top of the stove into the surrounding atmosphere.

WVith these and other objects in view, the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims and in the drawings illustrative of the preferred embodiment of the invention.

In the accompanying drawing:

Figure 1 represents a vertical section of a stove equipped with this improvement.

Fig. 2 is a horizontal section taken on the line 2-2 of Fig. 1, and

Fig. 3 is a similar view taken on the line 3-3 of Fig. 1.

In the embodiment illustrated a stove 1 is shown of ordinary construction having the usual base 2 supported by legs 3 equipped with the ordinary ash chamber 4: having a grate 5 supported thereover below the fire bowl 6. The top of the ash chamber is equipped with the ordinary grate hangers 7 and with apertured' bolt receiving ears 8.

A top 9 is shown dome-shaped and has a central opening 9 therein with a pipe 16.

depending therefrom for a to be described.

Upright pipes 10 and 20 are arranged at opposite sides of the stove on the interior thereof and extend through the bottom 2 as is shown clearly in Fig. 1 and have purpose presently lateral extensions on their lower ends opening to the atmosphere as shown in Figs. 1 and 2. While two only of these pipes are shown obviously any desired number may be employed. These pipes extend upward Specificationof Letters Patent. Application filediNovember 3, 192-0.

through the ash chamber 4: andfire bowl (ito points near the top of the stove, pipe 10 having a laterally and obliquely disposed arm 11 at its upper end which merges into a laterally andinwardly extendingwarm 12 at its inner end. This arm 12 communicatcs with an arm 13 arranged transversely of the stove and having a lateral extension 1 1 at the end opposed to thatwhich is connected with the pipe arm 12 and from the extension 1 1 is a pipe 15 arranged parallel with pipe 13 and which discharges into the lower end of pipe 16 above referred to.

The pipe 20 which is arranged at a point diametrically opposite the pipe 10 has laterally extending obliquely disposed arm 21 which merges at its inner end into a lateral extension 22 from the inner end of which extends a pipe 23 arranged parallel with pipes l3 and 15, and having an inwardly and laterally disposed arm 24: merging into a pipe 25 which alines with pipe 15 and discharges into the pipe 16 at a point opposite pipe 15.

From the above description it will be obvious that the pipes 10 and 20 will conduct cold air admitted thereto from the lower-part of the stove up through the body of the stove to a point near the top where they merge into the (zig zag pipes above described, said zig zag pipes'being arranged across the upper end of the stove to subject the air contained therein to the heat in the fire bowl, the air so heated being discharged through pipe 16 and opening 9? into the surrounding atmosphere. This arrangement of pipes provides a hot air distribution system in addition to the heat ordinarily radiated from a stove ofthis character.

A plate 17 is preferably arranged over the discharge opening 9*- and operates as a deflector for directing the hot air discharged through opening 9' downward toward the floor thereby diffusing and distributing it to a better effect.

The preferred embodiment of the invention is disclosed in the drawings and set forth in the specification. but it will be understood that any modifications within the scope of the claims may be made in the class described; of laterally spaced vertically disposed air conducting pipes extending below the bottom of the stove and upthrough and above thefire bowl thereof, a

horizontally disposed connection between said pipes comprising a double U-shaped horizontally disposedpipe arranged transversely of the upper portion of the stove with the open U-shaped portions facing in oppositedirections and each having at the end of the outer arm thereof a substantially L-shaped pipe, one L-shaped arm extending in a direction opposite to that on the other,

the outer end of each L-shaped arm being connected with a vertically disposedpipe, and a pipe opening'through the top of the stove and communicating with the horizontally disposed pipe.

2. The combination with a stove of the class described; of air conducting pipes extending from the top to the bottom thereof on its interior and opening through the bottom of ,thestove the upper end of each of said pipes having a laterally and inwardly Einc'lined arm provided with an inwardly extending lateralextension, a transverse pipe communicating withthe inner end of said extension and provided with an inwardly WILLIAMP.
